To all whom it may concern;

Be it known that I, CHARLES D. SAXTON, a

- citizen of theUnited States, and a resident of lowing is a full, clear, and

Boise, in the county of Ada and State of Idaho have invented a new and Im roved Pumpless Steam-Sprayer of which t e folexact description.

The invention resides in certain new and, useful improvements in the tank and connections therefor forapplying a spraying solution, such solution for example, as is apfor the thorough mixing of the .solution while in the tank, as well as the heating thereof if desired.

with a sheet metal' casing 4.

Reference is to be had to the accompanying drawing forming a part of this specification, wherein is represented in central vertical section the preferred embodiment of my invention, parts being in elevation.

in carrying out my invention l employa tank 1 of suitable capacity, which is preferably in the nature of an upright, cylindrical body capable of withstanding considerable pressure. Within this tank is a central, vertical guide-rod '2 secured in any suitable manner at the ends of the tank and on which is guided a lloat 3, the latter consist ing of a wooden core or body sheathed over A thimble 5 passing centrally through the float and se cured by lock-nuts at its opposite ends forms a bearing on the rod 2 and prevents any angular movement of the float 'with respect to the tank when the liquid therein is splashed or agitated.

source ofsupply has a valve 7- and' connects with the top of the tank, and is also provided with a pressure-gage S and a branch pipe 9, the latter connecting it with the tank at a point near the bottom thereof. The branch Specification of Letters Patent. Application filed. December 18, 1907. Seria No. 407,065.

The diameter of the float is such that a slight space is left between' float.

pipe 9 has suitable controlling valves 10 placed respectively near the pipe 6 and near the point of discharge into the tank 1.;

Leading into the pi e 6 near its point of discharge into. the ta i 1 is 'a liquid or solution' supply pipe '11 havinga controlling valve 12.

' The tank 1 discharges when inoperation,

through a pipe 13 connected near its bottom. Controlling valves 14 regulate thejsuppl through this ipe, which is connected up Wit one "or more ii usual spraying nozzle. ny solid matter which may be in, or is used in the solution in the discharge pipe 13 by a strainer 16 arranged Patented Aug. 11,1908. k

ose 15 each rovided with the .70 the tank, isprevented from passing In the operation of the tank and connections, when the tank is empty the solution which has been mixed in a barrel or other vesseh is coupled up with the pipe 11 by a hose or in any other desired manner. Steam is then introduced into the tank by opening the valve 7 and the valves 14, or the steam may be introduced by 0 ening the valves'10 in the branch pipe 9. f desired to heat the solution before it is introduced into the tank, the valve 12 in the li( uid supply pi e should be opened. After all of the air as. been lib driven out of the tank and pipe 11 al'l of the F valves should be closed except the valve 12. Under these conditions, as the steam con- (lenses in the tank a vacuum is created which causes the liquid to flow through the pipe 11 into the tank by the suction developed.

When the tank is filled to the required oint, v

' between the chemicals which might be used in the solution, thevalves 10 are opened, admitting the steam to the tank through the branch pipe 9. The escape of the steam through this pipe also agitates any solid matter-which may collect in the bottom of the tank.

In supplying the spray pipes through the discharge pipe from the tank, the steam is introduced through the pipe 6 above the vents the wooden core or body from swel ing or cracking and the float shields the surface of thc'liqui'd from the steam, thus preventing the condensation of the steam by the contact with the solution should a cold solution be The metal sheathing on this float rethe liquid.

used. The tank and connections are of such 1 below the float, means for regulating said form that the entire apparatus may be loaded 1 supplies and a discharge leading from the on a wagon and transported to the place where it is'to be used.

The construction as described and illus trated, while being my preferred embodiment of the invention, may, nevertheless, be variously modified within the scope of the claims annexed.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

1. The combination of a tank adapted to hold a liquid, and steam supplies leading to the tank both above and below the level of 2. The combination of a tank, a float movany: mounted within the tank, and steam .su plies leading to the tank both above and beiow the float.

ably mounted within the tank, steam supplies leading into the tank both above and tank near the bottom thereof.

4. The combination of a tank having a float movably mounted therein, a steam supply and a liquid supply leading to the tank above the float, and a discharge leading from the tank below the float.

5. The combination of a tank having a float movably mounted therein, a steam supply and a liquid supply leading into the tank above the float, a pressure gage carried bysaid steam supply, a second steam supply leading into the tank below the float, and a discharge havin a strainer leading from the tank below the float.

In testimony whereof I have signed my
